`AArch64InstrInfo::getInstSizeInBytes` does not take XRay instrumentation opcodes into account.
The default case of this function unconditionally returns 4, except for size definitions specified by TableGen.
However, on AArch64, the XRay pseudo-instructions expand to 32 bytes.
Since the XRay pseudo-opcodes are target-independent, the TableGen path doesn't get hit and therefore the size returned is wrong.
